Quick Start

This guide will show you how to set up a simple application using Node.js and MongoDB. Its scope is only how to set up the driver and perform the simple CRUD operations. For more in-depth coverage, see the tutorials.

Create the package.json file

First, create a directory where your application will live.

mkdir myproject
cd myproject

Enter the following command and answer the questions to create the initial structure for your new project:

npm init

Next, install the driver dependency.

npm install mongodb --save

You should see NPM download a lot of files. Once it’s done you’ll find all the downloaded packages under the node_modules directory.

The method updates the first document where the field a is equal to 2 by adding a new field b to the document set to 1. Next, update the callback function from MongoClient.connect to include the update method.
